Problems with random access in standalone (IFOUpdate issue?)

[Matthew]

I recently backed up a 2 disc DVD set, using CCE/Scenarist/IFOUpdate/IFOedit (latter for correct VTS sectors). In IFOUpdate 0.72 only the first 2 options were checked.

Here is the structure of disc 2 (backup), the structure of disc 1 is the same (except for times).

PGC_1 (program chain): [Title(TTN): 1] [00:51:58.00 / 25 fps] (Programs: 6) (Cells: 6) (uses VOB-IDs: 1)

PGC_4 (program chain): [Title(TTN): 4] [00:00:00.12 / 25 fps] (Programs: 1) (Cells: 1) (uses VOB-IDs: 3)
[Ch 01] [Pg 01] [Cell 01] [V/C Id: 3/ 1] : time: 00:00:00.12 / 25 fps [Pos: 00:00:00.12] [Frames: 12]

With the exception of PGC4 - which was originally a 22 second logo/warning played after ep 3 and which I replaced with a 12 frame clip, the chapters and times are exactly the same in the backup as the original.

Anyway, here's the problem:
-In disc 1, PGC1 entering in a value to skip to doesn't work if that value is less than 6:16. Inputting any value in before that results in the player just freezing at the currently displayed point. All values including 6:16 and after are fine. PGCs 2 and 3 have no such issues.
-In disc 2, the same is observed in PGC1 only, except for 22:14 and the values before it.

Fast forward and rewind, skipping between chapters etc is all fine.

This problem is not present in the original.

Is this a known issue at all?

Using the "VTS_TMAPTI table transfer option" in IFOUpdate appears to resolve the problem.

Also, if the dump option is used, this random access is unavailable at all.

Using the "VTS_TMAPTI table transfer option" in IFOUpdate appears to resolve the problem. Are you saying that you no longer have the problem?



...backed up a 2 disc DVD set, using CCE/Scenarist/IFOUpdate/IFOedit (latter for correct VTS sectors).So, I guess, this is not the original configuration. What did you do to change it?

[Matthew]

Yeah using that option did remove the problem...the IFOUpdate readme said it only related to software DVD players and it wasn't checked by default so originall I thought it best to leave it that way.

I backed up a 2 disc set on 2 discs, so no I did not change the structure =)

Glad it's solved.
